Zuhayr ibn Harb and Muhammad ibn al-Muthanna narrated to me, both saying: Yahya — namely al-Qattan — narrated to us. (Another chain:) Abu Bakr ibn Abi Shaybah narrated to us, saying: Abu Usamah and Ibn Numayr narrated to us, all of them from Ubaydullah, from Nafi', from Ibn Umar, from the Prophet (peace be upon him). (Another chain:) Yahya ibn Yahya narrated to us — and the wording is his — saying: I recited before Malik, from Nafi', from Ibn Umar, that the Prophet (peace be upon him) said: "Whoever carries weapons against us is not of us."
